If you're in the market for a power bank that can keep up with the high energy demands of gaming handhelds like the Steam Deck or ROG Ally X, Amazon is currently offering a stellar deal. You can snag the Anker PowerCore 737 24,000mAh 140W Power Bank for just $49.99. This deal is available through Woot, a marketplace vendor owned by Amazon, and it undercuts the lowest price we've previously seen by about $20. Having used this exact model for several years across multiple flights and road trips, I can confidently say it's a reliable choice that remains in excellent condition.

The Anker 737 is a top choice for charging the Steam Deck, being a robust power bank that measures 4.6"x2.2"x2" and weighs 1.4lbs. It's designed for travel bags or backpacks rather than pockets. This power bank features two USB Type-C ports and one USB Type-A port, with the USB Type-C ports capable of delivering up to 140W. This allows for configurations like 140W from a single port, or a combination such as 70W + 70W or 100W + 40W when multiple devices are connected.

When it comes to gaming handhelds, the Steam Deck requires up to 38W for charging, the Asus ROG Ally up to 65W, the Asus ROG Ally X up to 100W, and the Nintendo Switch up to 18W. The Anker 737 can charge all these devices at their maximum rates, allowing for simultaneous play and charge.

With a 24,000mAh battery, which translates to a 74Whr capacity, and an 80% power efficiency rating typical for power banks, you get approximately 59Whr of usable charge. This means the Anker 737 can fully charge a Steam Deck or Asus ROG Ally (both 40Whr) about 1.5 times, an Asus ROG Ally X (80Whr) about 0.75 times, and a Nintendo Switch (16Whr) around 3.7 times. This highlights why a 20,000mAh capacity is considered the minimum for power-hungry gaming handhelds.

The Anker 737 is TSA-approved

According to TSA regulations, power banks must have a capacity under 100Whr for carry-on luggage (check-in is prohibited). The Anker 737 comfortably fits within these limits at 74Whr. While its robust appearance might prompt occasional checks, I've personally cleared numerous airport checkpoints with this model, including a thorough check at Tokyo NRT, without any issues.
